No, you can't because it's a free testing site with limited SQL space and my search tables are so big. If you want, I'll update again next week but truncating the posts table in order to save space and to making you able to see the issue. Anyway and meanwhile, I tell you I guess the trouble is that the updating pack doesn't convert well the search tables to UTF8, which are still in latin1 and this is what makes troubles in a UTF8 database with spanish special chars like "á", "é", etc. In local I solved the issue copying the table from the old Icy database, so it's still in latin1, but it shows well.
Thanks for your attention,
MG.
